popt vulnerabilities

Vulnerability in the popt library allows an attacker to provide specially crafted configuration content that, when loaded, can lead to a small memory corruption issue due to an error in how the poptConfigFileToString function reallocates memory for buffers.

An integer underflow was found in the popt library when formatting help text for option tables wider than the terminal width. A local user who can cause an application to print help under those conditions may cause the application to crash or fail to display help, resulting in a denial of service.

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.
