CVE-2026-58472 2 Gnu, Wget 2 Wget, Wget 2026-07-14 5.9 Medium
GNU Wget through 1.25.0, fixed in commit dd692d9, contains a heap buffer overflow vulnerability in the html_quote_string() function in src/convert.c that allows a remote attacker to trigger memory corruption by supplying a crafted HTML attribute with a large number of characters requiring entity encoding. A server-supplied HTML attribute causes a signed integer counter to overflow during output size accumulation, resulting in an undersized heap allocation and subsequent heap buffer overflow during the copy phase.
CVE-2026-58470 2 Gnu, Wget 2 Wget, Wget 2026-07-14 5.3 Medium
GNU Wget through 1.25.0, fixed in commit 43d3ba9, contains an integer overflow vulnerability in the parse_content_range() function within src/http.c that allows server-controlled values to cause signed integer arithmetic to overflow. Attackers can supply malicious Content-Range header values to trigger undefined behavior and download desynchronization in the affected client.

CVE-2026-57433 2026-07-14 9.8 Critical
Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record. retrieve_hook_common reads a signed 32-bit item count from an SX_HOOK record and calls av_extend with that count plus one. A count of I32_MAX wraps the addition to a negative value. A crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization.
CVE-2026-57432 1 Shay 1 Perl 2026-07-14 8.4 High
Perl versions through 5.43.10 have an integer overflow in S_measure_struct leading to an out-of-bounds heap read in pack and unpack. S_measure_struct adds each item's size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the signed SSize_t total negative. The @, X, and x position codes then guard their moves with a signed length comparison that passes when the length is negative, advancing the buffer pointer out of bounds. A template derived from untrusted input can read heap memory past the buffer and return it to the caller.
CVE-2026-13221 1 Shay 1 Perl 2026-07-14 9.1 Critical
Perl versions through 5.43.9 produce silently incorrect regular expression matches when an alternation of more than 65535 fixed string branches is compiled into a trie in Perl_study_chunk. When such branches are combined into a trie, the delta between the first branch and the shared tail is stored in a 16-bit field. A branch count above 65535 overflows the field, and the trie's match decision table is truncated with no warning or error. A pattern of this shape produces false positive matches (matching strings it should not) and false negative matches (failing to match strings it should). When such a pattern gates an access or filtering decision, the result is wrong.
CVE-2023-45853 3 Redhat, Smihica, Zlib 3 Jboss Core Services, Pyminizip, Zlib 2026-07-14 8.8 High
MiniZip in zlib through 1.3 has an integer overflow and resultant heap-based buffer overflow in zipOpenNewFileInZip4_64 via a long filename, comment, or extra field. NOTE: MiniZip is not a supported part of the zlib product. NOTE: pyminizip through 0.2.6 is also vulnerable because it bundles an affected zlib version, and exposes the applicable MiniZip code through its compress API.
CVE-2025-14087 2 Gnome, Redhat 15 Glib, Ai Inference Server, Discovery and 12 more 2026-07-13 5.6 Medium
A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings.
CVE-2026-57156 1 Freerdp 1 Freerdp 2026-07-13 8.8 High
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0 on 32-bit builds, FreeRDP clients contain an integer overflow in update_read_delta_points in libfreerdp/core/orders.c when multiplying an attacker-controlled point count by sizeof(DELTA_POINT), allowing a malicious RDP peer to allocate an undersized heap buffer and then write beyond it during initialization. This issue is fixed in version 3.28.0.
CVE-2026-15551 1 Samsung Open Source 1 Rlottie 2026-07-13 5.5 Medium
Integer overflow or wraparound vulnerability in Samsung Open Source rlottie allows Overflow Buffers. This issue affects .
CVE-2026-59089 2 Gnome, Redhat 2 Gimp, Enterprise Linux 2026-07-13 5.5 Medium
A flaw was found in GIMP. The PlayStation TIM loader, responsible for handling PlayStation image files, incorrectly calculates the size of the Color Look-Up Table (CLUT) due to an integer overflow. This occurs when multiplying num_colors and num_cluts, both 16-bit unsigned short integers, resulting in a value exceeding the maximum integer limit. An attacker could exploit this by providing a specially crafted image file, leading to undefined behavior and causing the GIMP plug-in to abort, effectively resulting in a denial of service.
CVE-2026-40468 1 Gnu 1 Gawk 2026-07-13 N/A
Integer overflow vulnerability has been found in "builtin.c" program file of gawk. This issue may lead to memory exhaustion on the hosting operating system and could be used to overwrite gawk heap metadata and objects with attacker-controlled bytes. It affects gawk in versions 5.4.0 and below.
CVE-2026-38076 1 Artifex 1 Jbig2dec 2026-07-12 7.5 High
An integer overflow in the jbig2_arith_iaid_ctx_new() function of Artifex commit cc37d0 allows attackers to cause a Denial of Service (DoS) via a crafted input.
