2 security issues in sid high

There are 2 open security issues in sid.

2 important issues:
  • CVE-2026-95619: A flaw was found in libstdc++. An integer overflow can occur when processing large inputs to the aligned operator new in the C++ library. This vulnerability could lead to an undersized memory allocation, potentially causing memory corruption or application instability.
  • CVE-2026-102010: A flaw was found in GCC. When an application calls the erase_if function on a binary heap priority queue in libstdc++, the library reallocates storage but fails to update its internal entry pointer. An attacker capable of triggering this operation can exploit this use-after-free condition, leading to a Denial of Service (DoS) via an application crash or potential memory corruption.

    • ∙ ∙ Lintian check waiting for test results on riscv64 - info
    • ∙ ∙ Too young, only 4 of 5 days old
    • Additional info (not blocking):
    • ∙ ∙ Updating gcc-12 will fix bugs in testing: #1149818
    • ∙ ∙ Piuparts tested OK - https://piuparts.debian.org/sid/source/g/gcc-12.html
