    CVE-2026-18743 (GCVE-0-2026-18743)

    Vulnerability from nvd – Published: 2026-09-01 00:57 – Updated: 2026-09-08 22:53
    VLAI
    Title
    Popt-devel: popt-static: short realloc in poptconfigfiletostring
    Summary
    A flaw was found in popt. This vulnerability allows an attacker to provide specially crafted configuration content to a host, which, when loaded, can lead to a small memory corruption issue. This occurs because of an error in how the `poptConfigFileToString` function reallocates memory for buffers. Successful exploitation could result in heap metadata corruption, potentially causing the affected process to become unavailable (denial of service).

    Title
    Popt-devel: popt-static: size_t underflow in singleoptionhelp
    Summary
    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 (GCVE-0-2026-18739)

    Vulnerability from nvd – Published: 2026-08-04 05:32 – Updated: 2026-08-31 17:19
    VLAI
    Title
    Popt-devel: popt-static: off-by-one in poptstuffargs
    Summary
    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.

    CVE-2026-18743 (GCVE-0-2026-18743)

    Vulnerability from cvelistv5 – Published: 2026-09-01 00:57 – Updated: 2026-09-08 22:53
    VLAI
    Title
    Popt-devel: popt-static: short realloc in poptconfigfiletostring
    Summary
    A flaw was found in popt. This vulnerability allows an attacker to provide specially crafted configuration content to a host, which, when loaded, can lead to a small memory corruption issue. This occurs because of an error in how the `poptConfigFileToString` function reallocates memory for buffers. Successful exploitation could result in heap metadata corruption, potentially causing the affected process to become unavailable (denial of service).

    Popt-devel: popt-static: size_t underflow in singleoptionhelp
    Summary
    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 (GCVE-0-2026-18739)

    Vulnerability from cvelistv5 – Published: 2026-08-04 05:32 – Updated: 2026-08-31 17:19
    VLAI
    Title
    Popt-devel: popt-static: off-by-one in poptstuffargs
    Summary
    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.
