CVE-2026-18839 2 Popt-devel, Redhat 6 Popt-static, Enterprise Linux, Hardened Images and 3 more 2026-08-07 2.2 Low
An integer underflow was found in the popt library when formatting help text for option tables that exceed the terminal width. A local user who can cause an application to print help under those conditions may cause that application to crash or fail to display help, resulting in a denial of service of the affected application.
CVE-2026-18739 2 Popt-devel, Redhat 4 Popt-static, Enterprise Linux, Hummingbird and 1 more 2026-08-05 2.5 Low
A flaw was found in popt, a command-line option parsing library. An off-by-one error in the poptStuffArgs function, when repeatedly called by a host application or through deep alias nesting, can lead to corruption of internal program data. This corruption could potentially enable a local attacker to execute arbitrary code if the host application then unsafely processes the altered data.
