Threats tagged 'ghsa-grvf-fp92-82c6'

A vulnerability in libstdc++ causes a buffer overflow when a byte-by-byte write operation fails during file stream processing. This flaw can lead to denial of service or memory corruption if an attacker induces repeated write failures in a service that uses the vulnerable routines. Exploitation requires specific application designs and the ability to force repeated filesystem write errors while controlling individual character writes. Standard system utilities and privileged binaries are not affected. The vulnerability has a moderate impact rating and a CVSS score of 4.2.
