CVE-2023-6779 3 Fedoraproject, Gnu, Redhat 3 Fedora, Glibc, Enterprise Linux 2026-05-12 8.2 High
An off-by-one heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when these functions are called with a message bigger than INT_MAX bytes, leading to an incorrect calculation of the buffer size to store the message, resulting in an application crash. This issue affects glibc 2.37 and newer.
CVE-2023-6246 3 Fedoraproject, Gnu, Redhat 3 Fedora, Glibc, Enterprise Linux 2026-05-12 8.4 High
A heap-based buffer overflow was found in the __vsyslog_internal function of the glibc library. This function is called by the syslog and vsyslog functions. This issue occurs when the openlog function was not called, or called with the ident argument set to NULL, and the program name (the basename of argv[0]) is bigger than 1024 bytes, resulting in an application crash or local privilege escalation. This issue affects glibc 2.36 and newer.
CVE-2023-4806 3 Fedoraproject, Gnu, Redhat 24 Fedora, Glibc, Codeready Linux Builder Eus and 21 more 2026-05-12 5.9 Medium
A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags.
CVE-2023-4527 4 Fedoraproject, Gnu, Netapp and 1 more 32 Fedora, Glibc, H300s and 29 more 2026-05-12 6.5 Medium
A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.

The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.

CVE-2023-46219 3 Fedoraproject, Haxx, Redhat 3 Fedora, Curl, Jboss Core Services 2026-05-12 5.3 Medium
When saving HSTS data to an excessively long file name, curl could end up removing all contents, making subsequent requests using that file unaware of the HSTS status they should otherwise use.
CVE-2023-46218 3 Fedoraproject, Haxx, Redhat 7 Fedora, Curl, Enterprise Linux and 4 more 2026-05-12 6.5 Medium
This flaw allows a malicious HTTP server to set "super cookies" in curl that are then passed back to more origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get sent to different and unrelated sites and domains. It could do this by exploiting a mixed case flaw in curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though `co.uk` is listed as a PSL domain.
CVE-2023-38545 5 Fedoraproject, Haxx, Microsoft and 2 more 19 Fedora, Libcurl, Windows 10 1809 and 16 more 2026-05-12 8.8 High
This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due to this bug, the local variable that means "let the host resolve the name" could get the wrong value during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target buffer instead of copying just the resolved address there. The target buffer being a heap based buffer, and the host name coming from the URL that curl has been told to operate with.
CVE-2023-27043 4 Fedoraproject, Netapp, Python and 1 more 7 Fedora, Active Iq Unified Manager, Ontap Select Deploy Administration Utility and 4 more 2026-05-12 5.3 Medium
The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special character. The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some applications, an attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be used for signup). This occurs in email/_parseaddr.py in recent versions of Python.
CVE-2021-41617 6 Fedoraproject, Netapp, Openbsd and 3 more 15 Fedora, Active Iq Unified Manager, Aff 500f and 12 more 2026-05-12 7.0 High
sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges associated with group memberships of the sshd process, if the configuration specifies running the command as a different user.
CVE-2008-3252 2 Fedora, Redhat 2 Newsx, Fedora 2026-04-23 N/A
Stack-based buffer overflow in the read_article function in getarticle.c in newsx 1.6 allows remote attackers to execute arbitrary code via a news article containing a large number of lines starting with a period.
CVE-2008-2944 3 Fedoraproject, Linux, Redhat 3 Fedora Core, Linux Kernel, Enterprise Linux 2026-04-23 N/A
Double free vulnerability in the utrace support in the Linux kernel, probably 2.6.18, in Red Hat Enterprise Linux (RHEL) 5 and Fedora Core 6 (FC6) allows local users to cause a denial of service (oops), as demonstrated by a crash when running the GNU GDB testsuite, a different vulnerability than CVE-2008-2365.
CVE-2008-1677 1 Redhat 2 Directory Server, Fedora Directory Server 2026-04-23 N/A
Buffer overflow in the regular expression handler in Red Hat Directory Server 8.0 and 7.1 before SP6 allows remote attackers to cause a denial of service (slapd crash) and possibly execute arbitrary code via a crafted LDAP query that triggers the overflow during translation to a regular expression.
CVE-2007-4000 3 Fedoraproject, Mit, Redhat 3 Fedora, Kerberos 5, Enterprise Linux 2026-04-23 N/A
The kadm5_modify_policy_internal function in lib/kadm5/srv/svr_policy.c in the Kerberos administration daemon (kadmind) in MIT Kerberos 5 (krb5) 1.5 through 1.6.2 does not properly check return values when the policy does not exist, which might allow remote authenticated users with the "modify policy" privilege to execute arbitrary code via unspecified vectors that trigger a write to an uninitialized pointer.
CVE-2006-7151 2 Gnu, Redhat 2 Libtool-ltdl, Fedora Core 2026-04-23 N/A
Untrusted search path vulnerability in the libtool-ltdl library (libltdl.so) 1.5.22-2.3 in Fedora Core 5 might allow local users to execute arbitrary code via a malicious library in the (1) hwcap, (2) 0, and (3) nosegneg subdirectories.
CVE-2009-1837 4 Debian, Fedoraproject, Mozilla and 1 more 9 Debian Linux, Fedora, Firefox and 6 more 2026-04-23 7.5 High
Race condition in the NPObjWrapper_NewResolve function in modules/plugin/base/src/nsJSNPRuntime.cpp in xul.dll in Mozilla Firefox 3 before 3.0.11 might allow remote attackers to execute arbitrary code via a page transition during Java applet loading, related to a use-after-free vulnerability for memory associated with a destroyed Java object.
CVE-2007-6427 8 Apple, Canonical, Debian and 5 more 12 Mac Os X, Ubuntu Linux, Debian Linux and 9 more 2026-04-23 N/A
The XInput extension in X.Org Xserver before 1.4.1 allows context-dependent attackers to execute arbitrary code via requests related to byte swapping and heap corruption within multiple functions, a different vulnerability than CVE-2007-4990.
CVE-2009-0180 2 Nfs, Redhat 2 Nfs-utils, Fedora 2026-04-23 N/A
Certain Fedora build scripts for nfs-utils before 1.1.2-9.fc9 on Fedora 9, and before 1.1.4-6.fc10 on Fedora 10, omit TCP Wrapper support, which might allow remote attackers to bypass intended access restrictions, possibly a related issue to CVE-2008-1376.
CVE-2006-6235 6 Gnu, Gpg4win, Redhat and 3 more 9 Privacy Guard, Gpg4win, Enterprise Linux and 6 more 2026-04-23 N/A
