PGV-2676809 is a category 1 vulnerabilty that affects the following packages:
The risk assessment shows that this vulnerability is exlpoited by a compromised user. A legitimate user who unknowingly triggers exploitation of this vulnerability through normal interaction.
The impact is contained to the application. Exploitation remains confined to the application and cannot affect the host environment or external systems.
The threat damage is caused by a denial of service (limited). Exploitation can degrade or intermittently disrupt application availability without causing a full outage.is caused by a data breach (limited). Exploitation does not provide access to data beyond what the user is already authorized to access.
A flaw was found in libarchive. An attacker can cause a Denial of Service (DoS) or potential information disclosure due to a use-after-free vulnerability, which occurs when a program reads memory that has already been released. This issue arises when the archive_entry_copy_mac_metadata() function deallocates an internal buffer before completing a data copy. An attacker who can supply input to an application utilizing this function can trigger the flaw to crash the application or read uninitialized memory data.
