The version of rust installed on the remote host is prior to 1.68.2-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2496 advisory.
libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Using well-crafted inputs to git_revparse_single
can cause the function to enter an infinite loop, potentially causing a Denial of Service attack in the calling application. The revparse function in src/libgit2/revparse.c
uses a loop to parse the user-provided spec string. There is an edge-case during parsing that allows a bad actor to force the loop conditions to access arbitrary memory. Potentially, this could also leak memory if the extracted rev spec is reflected back to the attacker. As such, libgit2 versions before 1.4.0 are not affected. Users should upgrade to version 1.6.5 or 1.7.2. (CVE-2024-24575)
libgit2 is a portable C implementation of the Git core methods provided as a linkable library with a solid API, allowing to build Git functionality into your application. Using well-crafted inputs to git_index_add
can cause heap corruption that could be leveraged for arbitrary code execution. There is an issue in the has_dir_name
function in src/libgit2/index.c
, which frees an entry that should not be freed. The freed entry is later used and overwritten with potentially bad actor-controlled data leading to controlled heap corruption. Depending on the application that uses libgit2, this could lead to arbitrary code execution. This issue has been patched in version 1.6.5 and 1.7.2. (CVE-2024-24577)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
