A flaw was found in libgit2 before version 0.27.3. A missing check in git_delta_apply function in delta.c file, may lead to an out-of-bound read while reading a binary delta file. An attacker may use this flaw to cause a Denial of Service. Se ha descubierto un problema en versiones anteriores a la 0.27.3 de libgit2. La falta de una comprobación en la función git_delta_apply en el archivo delta.c puede conducir a una lectura fuera de límites mientras se lee un archivo delta binario. • https://bugzilla.redhat.com/show_bug.cgi?id=1598024 https://github.com/libgit2/libgit2/commit/9844d38bed10e9ff17174434b3421b227ae710f3 https://github.com/libgit2/libgit2/releases/tag/v0.27.3 https://lists.debian.org/debian-lts-announce/2018/08/msg00024.html https://lists.debian.org/debian-lts-announce/2022/03/msg00031.html • CWE-20: Improper Input Validation CWE-125: Out-of-bounds Read •

A flaw was found in libgit2 before version 0.27.3. It has been discovered that an unexpected sign extension in git_delta_apply function in delta.c file may lead to an integer overflow which in turn leads to an out of bound read, allowing to read before the base object. An attacker may use this flaw to leak memory addresses or cause a Denial of Service. Se ha descubierto un problema en versiones anteriores a la 0.27.3 de libgit2. Se ha descubierto que una extensión sign inesperada en la función git_delta_apply en el archivo delta.c puede conducir a un desbordamiento de enteros que conduce a una lectura fuera de límites, lo que le permite leer antes del objeto base. • https://bugzilla.redhat.com/show_bug.cgi?id=1598021 https://github.com/libgit2/libgit2/commit/3f461902dc1072acb8b7607ee65d0a0458ffac2a https://github.com/libgit2/libgit2/commit/c1577110467b701dcbcf9439ac225ea851b47d22 https://github.com/libgit2/libgit2/releases/tag/v0.27.3 https://lists.debian.org/debian-lts-announce/2018/08/msg00024.html https://lists.debian.org/debian-lts-announce/2022/03/msg00031.html • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound CWE-194: Unexpected Sign Extension CWE-681: Incorrect Conversion between Numeric Types •
